Hi,

I want to know the procedure to extend the root file system in Linux .

How to extend the root file system?

Can we use lvextend command directly online to increase the root file system?

Will their be any effect on the server, if we increase the file system online using lvextend command?

What does resize2fs command do?

Please help me with the info.

Regards,
Aparna.

You can only extend the LV if the parent VG has spare space available.
resize2fs extends the filesystem on top of the LV http://linux.die.net/man/8/resize2fs
